Group dancing is a ubiquitous human activity that involves exertive synchronized
movement to music. It is hypothesized to play a role in social bonding, potentially via the release of endorphins, which are analgesic and rewardinducing, and have been implicated in primate social bonding. We used a 2 2 experimental design to examine effects of exertion and synchrony on bonding. Both demonstrated significant independent positive effects on pain threshold (a proxy for endorphin activation) and in-group bonding. This
suggests that dance which involves both exertive and synchronized movement
may be an effective group bonding activity.
